STAFF at Fitness First in Crewe are swapping their T-shirts and jogging bottoms for fancy dress as part of a series of days to mark the leap year and highlight the club’s charity efforts during 2012.

The gym is raising money for Sport Relief and on March 23 is staging a giant running event for its 1,800 members.

Staff and members will run a mile on the King George V playing fields at the back of the centre.

General manager Leah Tyson said: “Staff are dressing up at the end of every month to create a buzz round the club.

“The extra day of February was marked with a Roman day and at the end of March we will become Super Heroes. We’re encouraging members to get involved by offering a prize for the best fancy dress. It’s a bit of fun and gets people talking about what we are doing for charity.”

In 2011 the club raised more than £800 with sponsored events for Asthma UK and was an active supporter of the British Heart Foundation for two years before that.

Leah added: “We’re a thriving club and there’s a lot of community spirit among our staff and members.”
